Indeed a very good day for Android. Google finally stepped up in the smartphones patent war, and announced today that it has acquired Motorola for $40 per share of Motorola or a lump sum of $12.5 Billion.

The acquisition of Motorola Mobility, a dedicated Android partner, will enable Google to supercharge the Android ecosystem and will enhance competition in mobile computing. Motorola Mobility will remain a licensee of Android and Android will remain open. Google will run Motorola Mobility as a separate business.

Larry Page, CEO of Google, said, “Motorola Mobility’s total commitment to Android has created a natural fit for our two companies. Together, we will create amazing user experiences that supercharge the entire Android ecosystem for the benefit of consumers, partners and developers. I look forward to welcoming Motorolans to our family of Googlers.”

Google was to pay $4 billion for Nortel’s 6000 wireless patents. So, acquiring Motorola, doesn’t seem to be a bad trade, but in fact with Motorola’s Mobility’s patents, Google can now easily fight back the lawsuits. Page called out that patents were the biggest reason of Motorola Mobility acquisition.

Truly we have seen how Apple was happy of having Galaxy Tab being blocked in Australia and Europe. Also, in United States Apple won a patent infringement case against Android’s largest handset maker, HTC. Furthermore, Microsoft played its part by squeezing out the patent licencing fees from 5 Android manufacturers. But, now with the Google having Motorola Mobility, end of patent war seems to be possible, providing developers more freedom on Android platform.
